B-674G
GAOFE
The B-674G PVC cable wrap-around label is specifically designed for Data Center and Communication Systems, providing reliable and long-term cable identification in high-density server and network environments.
As a professional-grade solution within Data Center and Server Labels, this PVC label is engineered to wrap tightly around cables, forming a clear and durable identification surface without edge lifting or flagging. Its flexible Polyvinyl Chloride (PVC) construction ensures stable performance on Ethernet cables, power cords, patch cords, and communication lines commonly used in data centers and server rooms.
Durable PVC (Polyvinyl Chloride) Material
Offers excellent flexibility, abrasion resistance, and mechanical strength for continuous use in data center environments.
Wrap-Around Cable Identification Design
Designed to wrap and overlap on itself, creating a secure bond ideal for round cables and high-density cable bundles.
Optimized for Data Center and Server Labels
Maintains legibility and adhesion in server racks, cabinets, and communication closets.
Clear Print Performance
Supports barcode, alphanumeric codes, port numbers, and network identifiers for accurate cable tracing.
Reliable Adhesion for Communication Systems
Adheres firmly to common cable jackets without slipping, curling, or detaching over time.
Data Center Cable Management
Used for identifying Ethernet cables, power cables, and patch cords in server racks and cabinets.
Communication Systems Identification
Ideal for structured cabling systems in telecom rooms, network operation centers, and communication hubs.
Server Room & Rack Labeling
Supports efficient maintenance, troubleshooting, and expansion in complex server infrastructures.
Network Infrastructure Projects
Suitable for new installations, upgrades, and retrofitting of data center and communication systems.
